# What was the question to which Max Planck gave an explanation and how is it related to blackbody radiation?

Quoting from my text book - "several attempts were made to predict intensity as a function of temperature/wavelength". This line was preceded by the explanation for blackbody radiations and about how the intensity of radiation of a particular wavelength would be maximum at a particular temperature.

This was followed by "Planck gave a satisfactory relationship by assuming that absorption and emission of waves arises from oscillators I.e., atoms in the wall of the blackbody. He suggested that radiation could be sub divided into discrete chunks of energy, he gave the name quantum to the smallest quantity of energy that can be absorbed or emitted".

I am aware of the equation Energy=frequency x Planck's constant

How does Planck's above explanation correlate with intensity being a function of wavelength or temperature? How does it have a relation to blackbody radiation?

Ps:- I'm a student of 10th grade so please do try to keep the explanation simple.. :-)
